It was a move that shouldn't have gone wrong. Nuri Sahin arrived at Real Madrid as the best player in Germany and a Bundesliga champion, ready to prove himself at the highest level and announce himself as the natural successor to Xabi Alonso.
A little under two years later, he is back at Signal Iduna Park after a failed loan spell at Liverpool, having struggled to establish himself in any way, shape or form at the Santiago Bernabeu.
He may have returned home, but Sahin does not look to be the player who left BVB - yet. The Turkey international has demonstrated his genius but his ordeal away from the club seems to have shattered his confidence and fitness.
